ABSTRACT:
A sprayable, modified polyisocyanurate solid or foam composition, with fast reaction times and excellent fire properties and capable of being sprayed in a one-to-one, fixed-volume spray system, is prepared by the reaction of a low-functionality MDI, with a polyol composition comprising a methoxy polyethylene glycol and a methyl glucoside polyol, the reaction carried out in the presence of a trimerization catalyst, to provide a sprayable polyisocyanurate composition particularly useful for spraying upright and overhead surfaces, due to the fast reaction time and rapid cure.
